I agree.  Much to my dismay, the C and C++ committees don't seem to be 
willing to work together to make sure that C remains a subset of C++. 
I'm not terribly familiar with this proposal.

Ben, to answer your original question, I don't think that lack of nested 
address spaces is a fatal flaw, as long as the implementation otherwise 
meets the spec, and as long as the implementation doesn't somehow make 
it harder to add that.  However, I'd like to know how final this 
proposal is, and how likely it is to make the WG14 WP.  As always, I'm 
concerned about putting things into GCC and then finding out that we 
have to change them in ways that are not backwards compatible.  And, I'd 
like to know what our C maintainers make of the proposal overall; if 
they see language issues, then we might want to resolve those with WG14.

Thanks,
